<h2>Reaction Times to Audio and Visual Stimuli</h2>

<h3>Description</h3>

<p>Data from an experiment on reaction times to audio or visual stimuli by Oberlin College students.
</p>


<h3>Format</h3>

<p>A data frame with 72 observations on the following 4 variables.
</p>

<dl>
<dt><code>Subject</code></dt><dd><p>SubjectIDs coded <code>s1</code> to <code>s36</code></p>
</dd>
<dt><code>ResponseTime</code></dt><dd><p>Time to respond to a stimulus (in ms)</p>
</dd>
<dt><code>Stimulus</code></dt><dd><p>Type of stimulus  (<code>auditory</code> or <code>visual</code>)</p>
</dd>
<dt><code>Group</code></dt><dd><p><code>Musician</code> or <code>NonMusician</code></p>
</dd>
</dl>



<h3>Details</h3>

<p>Subjects in a reaction time study were asked to press a button as fast as possible after being exposed to either an auditory stimulus (a burst of white noise) or a visual stimulus (a circle flashing on a computer screen).  Average reaction times (ms) were recorded for between 10 and 20 trials for each type of stimulus for each subject. Data also identifies which subjects are musicians.
